OIL-,GAS LAM P.

SPECIFICATION forming part of Letters Patent No. 625,630, dated May 23, 1899.

Application led January 14, 1899. Serial No. 702,179. (No model.)

To @ZZ whom it may concern:

Be it known that I, JAMES A. YAETON, of Omaha, in the county of Douglas and State of Nebraska, have invented a new and lmproved-Oil-'Gas Lamp, of which the following is a full, clear, and exact description.

My invention relates to an improvement in oil-gas lamps, or lamps of .that kind which use oil for fuel, but ltransform it into gas before burning.

My invention comprises an improved form of generator and shield therefor, together with a method of supporting the lamp so that it may be swung to one side, and thus drawn from under vthe generator.

My invention also comprises an improved construction of the controlling-valve, whereby any sediment which may be in the oil isl prevented from entering the generatoretube. My invention further comprises the novel Afeatures hereinafter described and claimed. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indie cate corresponding parts in all the figures.

Figure l` is an elevation of my lam-p withA portions thereof shown in section. Fig. 2 isi a sectional elevation, on a larger scale, of thei controllingwalve and the swivel-support fori the lamp. Fig. 3 is a section taken upon thei line 3 3 of Fig. l, with the lamp swung to onei side, so as to clear the generator; and Fig. 4 is an end view of the shield covering the gen` erator-tube. The lamp is intended for use in connection with an incandescent mantle, the burner it` self being, however, of the ordinary form.` The oil is contained in an elevated reservoir C, which is supported from a feed-tube A by means of a brace a' and by the supply-tube C', which connects the lower end of the reservoir with the feeding-tube A, which connection is made by means of an ordinary T A. A continuation A2 of the feeding-pipe extends downward and is screwed or otherwise secu red to the valve-casing B, which is shown in secftion and on an `enlarged scale in Fig. 2, and is provided with an upwardlyextending sleeve B', threaded interiorly to receive the 5o tube A2, and is also provided with a horizon tally-extending sleeve B2, which is interiorly threaded to receive the generator-tube H. The casing has a central passage or chamber E, which is in line with the feeding-tube A2. This passage or chamber Vis extended upward into the feeding-tube A2 by means of a short section of smaller tube D, which provides a chamber between the small tube D and the feeding-tube A2, designed to catch and hold any sediment which may be in the oil and 6o prevent its access to the generator. Surrounding the chamber E, within the valvecasing, and having adividing-wall between the two is an annular chamber E, connected at its upper end by a passage E2 with the 65 generator-tube H. Connection is made between the two chambers E and E by means of a conical aperture extending through the separatingepartition near theupper portion of each chamber. This aperture is placed as 7o far as convenient above the bottom of each chamber, so as to furnish further settlingchambers for the reception of any sediment which may be carried by the oil. The conical connecting-aperture is controlled by a valve F, consisting of a threaded rod screwed into a sleeve B3 of the valve-casing and having a pointed end fitting the conical aperture. The stem of the valve is packed by means of a packing-sleeve F, which screws upon the 8o outer end of the sleeve B3.

The generator consists of a tube l-I, bent backward upon itself, as clearly shown in Fig. 1. The outer end of said tube is carried at a slightly-greater elevation than a portion 8 5 of the tube near the bend, said lowermost portion of the tube being located directly over the lamp-chimney when the lamp L is in the normal position, and thus a small reservoir is provided for any oil which may re- 9o main in the tube unvolatilized. Within the tube are one or more spiral .coils of wire h, formed of copper or any other good heat-conducting material. As herein shown, this inner heat-conducting coil is formed of several spiral coils of wire. The same end might be secured by the use of a single wire, placing the coils of the wire close together. The outer end of the tube H is closed by a hollow plug H', which screws into the end of the tube and roo 'I has a perforation h for the escape of the gas.

The spiral wires h extend close enough to the end of the tube so that the plug I-I when screwed in place will press against the ends of the wires. The end of the generator-tube is placed in front of the receiving end of the mixing-tube I, and the upper portion of this mixing-tube is formed as a part of a casting G, which mayeither form a part of the valvecasing B or, as shown in Fig. 1, be made separate therefrom and secured thereto. In Fig. 2 it is shown as secured to the valve-casing by means ot' a socket G', which is interiorly threaded and screws upon a projecting plug B4 of thevalve-casing. To the lower end of this casting is secured the mixing-tube proper, I, which extends downward and then curves horizontally and upward, carrying upon its lower end the burner and lamp L. The tube I is supported by a swivel-joint, so that it may be turned upon its axis and the lamp swung from beneath the generator. The upper end ot' the tube I is provided with a collar I OslightIy-larger diameter than the tube andv which is engaged by the lower end of a cap J, which screws upon the casting G, as shown at g. This connection serves to support the tube and hold its upper end against the casting G. For the purpose of making a tighter joint the casting G is provided with a groove I2, which receives the end of the tube I. To more iirmly support the tube I, the casting G is provided with a t downward a sufficient distance to form a firm support therefor. It will be seen that by this construction the lamp may be swung to one side, so as to clear it of the generator and enable the chimney to be readily removed. This position of the parts is shown in Fig. 3.

To better concentrate the heat upon the generator, it is covered by a shield, which is clearly shown in Figs. 1 and 4. This shield is in cross-section of a V shape and has its outer e'nd closed, the shield being placed immediately over the generator-tube. At the upper end of the shield it is provided with two arms 7c, which may be bent about the valve-casing B, so as to hold the shield in position. This concentrates and holds the heat about the generator-tube H, so as to more etliciently volatilize the oil.

The feeding-tube A may be provided at its upper end with a hook a, by means of which the lamp may be suspended.

It is evident that the burner may be swung from beneath the generator by permitting the casting G to turn upon the valve-casing B at the point where it is screwed thereon, thus doing away with the necessity of the swivel connection between the tube I and the casting G. The result accomplished, which is the removal of the lamp from beneath the generator, is the same as that accomplished by the swivel connection-previously described.

In this case, however, the hood K should be either broadened at its open end or made short enough so as to not interfere with the swinging of the receiving end of the mixingtube. This might also be-accomplished by shortening the projecting sleeve G2, which acts as the receiving end for the mixing-tube.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In an oil-gas lamp, a mixing-tube carrying a burner at one end, a gas-generator discharging into the other end ofthe mixing-tube, said mixing-tube being formed in two sections, one section having a iiange near its end and the'other having a groove to receive the end of the irst section and a reduced portion entering the said first section, and a clampingring engaging said flange and screwing upon the other section, substantially as described 2. A supply-valve for oil-gas generators, comprising a casing to which the supply and generator pipes are attached, provided with a central passage extended up in'to the supply-pipe and forming therewith and within the same an annular settling-chamber, and with a passage leading from the central passage to the generator-pipe, and a valve for controlling communication between the said passages, substantially as described.

3. A .supply-Valve for oil-gas generators, comprising a casing having attachments for the oil-supply and generator pipes at right angles to each other, said casing having a central passage or chamber, and an annular chamber surrounding the irst, andboth in line with the oil-supply connection, the central chamber being connected with the oilsupply and the annular chamber connected above its bottom with the generator, said casing having a connecting-passage between the central and the annular chambers, located above the bottom of each, whereby settlingchambers are formed, and a valve mounted in the casing and adapted to close said connecting-passage, substantially as described.

4. A supply-valve for oil-gas generators, comprising a casing having attachments for the oil-supply and generatorpipes, at right angles to each other, said casing having a central passage or chamber, and an annular chamber surrounding the iirst, both being in line with the oil-supply connection, the central chamber being extended upward into the oil-supply connection by a small tube, thus forming a settling-chamberabout said tube, the annular chamber being connected above its bottom with the generator, the casing having the connecting-passage between the central and annular chambers located above the bottom of each, whereby additional settlingchambers are formed, and a valve mounted in the casing and adapted to close said connecting-passage, substantially as described.

5. A generator, provided with a suitable heat-conducting filler, and a tip entering the IOO erator-socket, and a generator-tube inserted in said socket, of a Wire filler Within said tube extending to and contacting with the valve-seat, and a tip Within the other end of 15 the generator-tube and adjustable to contact with the Wire filler, substan tally as described.
